'To all swhom it .mog/.100120614711 .Be ait known that l, .Ninon-AY .MALMAN a citizen of 'the United fStates, residing at the :city and county :of :San ranciseo, :Land :State `of California, haveinvented '.new useful improvements vinllesilient Mheels, :of which fthe @following isy a specification.

"llhis :invention relates atoa resilientitire.

yOnefofithefbjects of the :present iiwention iis to Iprovid'e a ssimple, substantial, cheaply manufactured, :punctureeprfroi `gresilient faire for Vehicle Wheels, .rand :particularly :to :provide :a sectional `tire consistingof fa vplurality .of :shoes .which are )connected by :links and Asecured to 'the irini of the fit/.heel .aby a single chain of special .construction, :herein- ...aiter .to vlbe e described. yAnother :obj ect nl the *invention is :to preside resilient lmenibers v'which `are interposed :between each rindiyidual'tire-section and -.the rim, and :to promide `means .fopera'ble 2in conjunction A.with the connecting links and vthe :single chain 'specified for increasingorzdecreasingithe :refsiliency or 4tension between "the isections of Athe `ftire fand Athe rim. Eurther snlojects Vwill herein-after A:'appear.

v 'The :invention iconsists tot the fand fthe construction rand y=.combination 'of parts as hereinafter imore :fully "described :and

claimed havin'gfrerterencerofthe accnmpanying rdrawings, iin Which- Figure fl aside felexration, ipsntly "broken nwazy :und ipartly 1in section, showing -the construction of the resilient tire and `the wheel Lto .which it -isapplied n 'FigQis a cross section on the line 2 2 of Fig. 1.

Fig. 3 is a plan section, staken on the line 3 3 of Fig. l.

Referring to the drawings in detail, A in- 'dica'tes the rim for "telly -fof'the Wheel and 2 the spokes. Surrounding the exterior face of the telly is a continuous steel band or ring 3, and formed in the face 0f said band and the elly is a plurality of pockets 4 which serve as seats or receptacles for cushion members, such as indicated at 5. These members are preferably constructed of rubber and are spherical in shape.

Mounted exteriorly of the :telly and the ring 3 surrounding same is the resilient tire proper, which consists of a plurality of shoes, generally indicated at 6. Any suitable number of shoes may be employed and each shoe comprises a channel plate 8, between the lianges of which are secured. a

.suitable vnumber rofgkey bolts i9. iEachzshoe iis l:otlilerwise provided 'with a rubber :bleek l0 which is Vulcanizedin `positionand held :in :the .shoe .by :means nf itlie key .bolts 9. Eadhashoeiisialsox rovided on its .inner ,tace

with ia @bearing plate lil :riveted thereto, ithe outer ends :of which are turned :.doWn, .as at i2, "to .form fconneetions .for Tthe link-s igen- -zerally indicated .at .7 'which sWill fhereinaftter be described.

The inner rtace :of .each .shoe iis :pro'iiided 'with :a pair o zpockets :or depressions :tor the receptionroi 'the resilient :members z5 i and as/these depressions are formed in alinement with .the pockets 4, fiormed iin ithe `:rim and the :telly .of the wheehit yran readilyabe'seen 3. This chain consists .o'.the1links :14 tand intermediate .links 1:5 which `are pivot-.ally nomiected pinsfor :bolts .11.6. .The ends tof fthe linksl 1ar.e'`i`-'shajped, aas iindicated, to

by the ipins 15 form la fcomnlete '.innlosure lor each individual spoke, therebyfretainingnthe chain a Icentral position :and also gprerenting it from :sw-inging .ont .of talinement with the telly and :spokes '.Tfhe links i4 are centrally '-.enlarged :per- A orated :and `lthreaded 'der reception foi the bolts 13,1andias :nut-s 17 .are provided '.it becomes possible to draw the bolts, together with the 'llinks k7 .fandrthe .fsiroes 46 fatta'ched thereto, inwardly with relation to the felly, thereby compressing` the resilient members 5 and consequently increasing or decreasing the resiliency of the shoe-like tire surrounding the telly. The shoes, as shown in Fig. l, are only connected in pairs by the links 7 While the chain structure generally shown in Fig. 3 connects the pairs in series.

' Each shoe contained in the tire structure as a. Whole is permitted a free pivotal movement about the bearing lugs l2 and the outer ends of the links 7 thereby increasing the resiliency and the tractive quality of the tire. Practically any ,tension between the outer tire and the fellyinay be obtained by tightening'up the bolts` 13 to render displacement in a lateral direction impossible; such displacement being turtlier guarded against by the position ot the bolts 13 and the construction ot the chain shown in Fig. 3. That is, any tendency toward lateral displacement ot anyv shoe or number vot shoes with relation to the telly will cause the bolts 13 to engage the sides ot the rim and thereby limit lateral movement in either direction, this being also true ot the chain structure provided.

The tire as a whole may be replaced by providing new shoes or any individual shoe may be replaced as conditions may require.

The materials and iinish ot the several parts employed may also be such as the eX- perience and judgment ot the manufacturer may dictate.

IV wishvit understood that various changes in torm, proportions and minor details ot construction may be resorted to'within the scope ot the appended claims .and that I do not wish to limit myselt to the specific desigr and construction here shown. Y

aving thus described my invention, what I claim and desire to secure by Letters Patent is- 1. The combination with the telly ot a Wheel, ot a tire surrounding the telly, said tire comprising a plurality ot shoes, links vconnecting the shoes in pairs, means connecting each pair in series, and a pair ot yresilient members interposed between each 35 i shoe and the telly. Y

2. The combination with theV telly ot a wheel, ot a tire surrounding the telly, said tire comprising a plurality ot shoes, links connecting the shoes inV pairs, a lexible member, and means connecting the vlinks with the flexible member to connect the pairs in series.

3. The combination with the tellyot a wheel, ot a tire surrounding the telly, said tire comprising a plurality ot shoes, links connecting the shoes in pairs, a exible member, means connecting the links with the flexible member to connect the pairs in series, and eompressible members interposed between eachshoe and the telly. f

l. The combination with the telly ot a wheel, ot a tire surrounding the telly, saidY y tire comprising a plurality ot shoes, a pair ot resilient members interposed Vbetween each shoe and the telly, a pair ot bearing lugs centrallypositioned, one on each side 'ot eachv shoe, a pair ot links pivotally attached to said bearing lugs and connecting successive pairs ot shoes, and ay flexible connection between said links.V Y i Y 6. The combination with the Vtelly ot a wheel, ot a tire surrounding the telly, said tire comprising a plurality ot shoes, a pair ot resilient members interposed between each shoe and the telly, a pair ot bearing lugs centrally positioned, one on each side ot each shoe, a vpair ot links pivotally attached to said bearing lugs and connecting successive pairs ot shoes, a chain interiorly ot the telly consisting ot'double links positioned one on each side ot each spoke, single linksV pivotally connected `with Veach set ot double links and perforated enlargements` on each double link, Vand radially disposed rods threaded'on theirinner endsv extending through the perforated double links and secured therein by nuts and pivotally connected at their outerV ends to .the links connecting each successive pairot shoes.A
